Item OFR16-02, Industrial minerals of the Upper Midwest; Proceedings of the 51st Forum on the Geology of Industrial Minerals, presented in cooperation with the Annual Conference of the Twin Cities Subsection of the Society for Mining, Metallurgy & Exploration (SME), August 17 – 20, 2015(Minnesota Geological Survey, 2016) Thorleifson, L HarveyOn August 17 – 20, 2015, the Twin Cities Subsection of the Society for Mining, Metallurgy & Exploration (SME) hosted the 51st Forum on the Geology of Industrial Minerals. The theme of the meeting, whose conference sessions and field trips were enjoyed by about 100 people, was ‘Industrial minerals of the Upper Midwest’. SME, headquartered in Denver, is a professional society whose more than 15,000 membership represents all professionals serving the minerals industry in more than 100 countries. SME advances the worldwide mining and underground construction community through information exchange and professional development. In Minnesota, the SME Minnesota Section maintains a broad program of activities that focuses on the annual spring conference in Duluth. The SME Twin Cities Subsection organizes an annual autumn conference, monthly luncheons, student activities, and social functions. Following a hiatus, the SME Twin Cities Subsection annual conference was restarted in 2011. For 2012 and subsequent years, the subsection has worked with a different partner each year, to present a conference program aligned with broad mining-related topics, while focusing on the sort of mining that takes place in the Twin Cities region, such as crushed stone, sand and gravel, and silica sand. For 2015, the SME Twin Cities Subsection was pleased to work in cooperation with organizers of the Forum on the Geology of Industrial Minerals. The Forum meets regularly, and it has been customary for a proceedings volume to be produced. Among the 17 presenters who gave presentations at the 2015 Forum, seven chose to contribute a paper. The Minnesota Geological Survey is pleased to have an opportunity to support the activities of SME and the Forum by facilitating availability of the 2015 Proceedings of the 51st Forum on the Geology of Industrial Minerals.Item OFR18-01, Geologic Mapping Forum Abstracts(Minnesota Geological Survey, 2018) Thorleifson, L HarveyAt the Geologic Mapping Forum in Minneapolis from March 27th to 29th, 2018, ~100 geological map authors, program managers and allied professionals from geological surveys and allied agencies met to discuss the status and future of geologic mapping in the USA. The meeting was hosted by Minnesota Geological Survey on the University of Minnesota campus. The meeting was held near the Mississippi River, at the Humphrey School of Public Affairs on the West Bank campus, in the Humphrey School Conference Center at 301 19th Avenue South, Minneapolis, MN 55455. Unless they had been invited to speak in a plenary, all participants were urged to present a 15-minute talk in a concurrent session or a poster. Plenary, concurrent session, and poster presenters were asked to submit a 1 to 2-page abstract. The meeting commenced with registration and a reception at the hotel with light food and drinks on Monday from 5 to 7 PM, followed by conference sessions from 8:30 AM Tuesday until 4:30 PM Thursday.Item OFR19-1, Geologic Mapping Forum 2019 Abstracts(Minnesota Geological Survey, 2019) Thorleifson, L HarveyAt the Geologic Mapping Forum in Minneapolis from April 10th to 12th, 2019, ~100 geological map authors, program managers and allied professionals from geological surveys and associated agencies met to discuss the status and future of geologic mapping in the USA and neighboring countries. The meeting was hosted by the Minnesota Geological Survey on the University of Minnesota campus. The meeting was held at the Humphrey School of Public Affairs on the West Bank campus, in the Humphrey School Conference Center at 301 19th Avenue South, Minneapolis, MN 55455. Participants were invited to present a 30-minute plenary or 15-minute talk, or a poster, and submitted a 1 to 2-page abstract published in this Open File. The meeting opened with registration and a reception on Tuesday evening followed by conference sessions beginning at 8:30 AM Wednesday and ending 2:30 PM Friday. Regional organization business meetings followed on Friday afternoon and Saturday.Item OFR20-01, Minnesota Data Preservation Report for 2019/2020: Updated Data Inventory, Preservation of Pillsbury Hall Rock Collections and Documentation, Assembly of Mineral Potential Related Information(Minnesota Geological Survey, 2020) Thorleifson, L HarveyMinnesota Geological Survey (MGS) activity is focused primarily on recommendations of Legislative panels that indicate that statewide coverage of layered County Geologic Atlases will be needed to support management of water resources, while concurrently being needed for applications such as mineral resources, engineering, hazards, and research. All MGS activity is reliant on geological specimens, as well as geological, geophysical, and geochemical data. The MGS long-term data preservation plan prepared in 2009 identified the highest priorities in relation to applications such as groundwater management and mineral resource assessment. Included were: 1) reprocessing of the aeromagnetic database; 2) enhancement of location precision for gravity stations; 3) vertical georeferencing of the rock property database; 4) cataloging and georeferencing of rocks and thin sections stored at the building MGS occupied from 1983 to 2015; 5) standardized formats for existing databases; and 6) scan and web enable all publications. More recently, a need was recognized for: 7) scanning, digitizing, and enhanced cataloging of borehole geophysical records, 8) comprehensive regional geophysical survey rescue, 9) enhancements to the cuttings collection and database. Objectives 1, 2, and 3 were completed with State of Minnesota support. Objective 4 was completed with multiple years of NGGDPP support. Objective 5 is ongoing. Objective 6 was completed with University of Minnesota Library support. Objective 7 was completed for gamma logs with our 2015 NGGDPP grant, and was completed for all borehole geophysical logs due to 2017 NGGDPP support. Geophysical survey rescue will remain unfulfilled due to staff availability constraints. Work on cuttings will be carried out due to NGGDPP support during 2020/2021.Item OFR21-01, Geologic Mapping Forum 20/21 Abstracts(Minnesota Geological Survey, 2021) Thorleifson, L HarveyDue to the coronavirus pandemic, the Geologic Mapping Forum for 2020 and 2021 was held online as monthly meetings from October 2020 to April 2021. As many as 140 geological map authors, program managers and allied professionals from geological surveys and associated agencies attended, to discuss the status and future of geologic mapping in the USA and neighboring countries. The meeting was hosted by the Minnesota Geological Survey of the University of Minnesota. Participants were invited to present a 20-minute minute talk, and were given the option to submit a 1 to 2-page abstract published in this Open File.Item OFR22-01, Assessment of preservation needs and long-range plan for geologic collections and data in Minnesota; a report prepared in fulfillment of National Geological and Geophysical Data Preservation Program Award Number 07HQGR0126(Minnesota Geological Survey, 2009) Thorleifson, L HarveyAccording to the National Geological and Geophysical Data Preservation Program (NGGDPP) web site, section 351 of the Energy Policy Act of 2005 directs the Secretary of the Department of the Interior (DOI), through the Director of the U.S. Geological Survey (USGS), to carry out a National Geological and Geophysical Data Preservation Program. The Implementation Plan for the NGGDPP, submitted to Congress in August 2006, outlines the vision and purpose of the program and makes recommendations for its implementation. One of the early action items in the implementation plan is for USGS to begin interactions with State Geological Surveys and other DOI agencies that maintain geological and geophysical data and samples to address their preservation and data rescue needs. As the first step in this process, USGS requested that each state provide an assessment of current collection resources and data preservation needs, and thus provide a summary of the collections held, supported, or used by state geological surveys.Item OFR22-02, Geologic Mapping Forum 21/22 Abstracts(Minnesota Geological Survey, 2022) Thorleifson, L HarveyDue to the coronavirus pandemic, the Geologic Mapping Forum was again held online in 2021/2022, as monthly meetings from September 2021 to April 2022.
